SPECIFICATION forming part of Letters Patent-No. 659,099, dated October2, 1900. Application iiled November ll, 1899.1 Renewed August 2'7, 1900.Serial No. 28.246. (No model.)

To @ZZ whom t may concern:

Be it known that I, WINsToN KENT PEN DLETON, of Ocoee, in the county ofOrange and State of Florida, have invented a new and useful Improvementin Thill-Oouplings, of

which the following is a specification.

My invention is an improvement in thillcouplings, and has for its objecta device of this character which will be of comparativelyfew parts, easyto attach or detach from the axle, and with which the shaft or pole maybe quickly and securely coupled and easily uncoupled.

The invention consists in certain details of construction andarrangement of the parts, which will be hereinafter described andclaimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which like characters of reference indicatecorresponding parts in all the views.

Figure 1 is a rear perspective View of my improved thill-coupling. Fig.2 is a transverse section thereof. Fig. 3 is a detail view of boltemployed. Fig. 4 is a detail perspective View of the locking-lever. Fig.5 is a similar view of the locking-nut. Fig. 6 is a perspective view ofthe shackle. Fig. 7 is a similar view of the clip, and Fig. 8 is asimilar view of the pivot-pin.

The shackle l0 consists of a base-plate 11 and spaced-apart jaws 12,preferably formed of one integral piece of suitable metal. Near its rearend the base-plate is formed with an aperture 13, through which thelower threaded end of a cam-bolt 14 is arranged to loosely extend, saidbolt at its upper end being provided with a notch forming a shoulder15,- with which is adapted to engage the rear apertured end 16 of themetal clip 17. This clip 17 extends forwardly over the upper part of theaxle A, as shown in Figs. 1 and 2, and at its front end is formed withpreferably-integral apertured ears 18, adapted to engage with the upperrecessed ends 19 of the jaws l2 and with a spring extension 20,extending downwardly between said jaws, for a purpose to be hereinafterexplained.

On the threaded lower end of the bolt 14 screws a nut 21, havingtrunnions 22 inserted in suitable bearings in the bifurcated end of alocking-lever 23, said lever having cam-s urfaces 24, adapted to ride onthe lower face of the base-plate and lock the shackle securely to theaxle A when the locking-lever is turned up into the position shown inFig. 1, the arm of said lever in such position entering a recess 25 inthe rear edge of the base-plate. By this means the shackle is quicklysecured on the axle and may be quickly and easily 6o detached therefrom.

The shaft or pole B is formed with a noncircular opening B in its rearend, into which is inserted the flattened shank of the pivotpin 26,formed at one end with an integral oblong or flattened head 27 andscrew-threaded, at its other end to receive a second. oblong head 28.The rear end of the shaft or pole, with the pivot-pin 26 attached, isinserted between the jaws 12 in a vertical position, and 7o the heads 27and 28 enter vertical passages 29 in the jaws, of a width about equal tothe shortest diameter of the heads, the said passages being widened atthe bottom to form bearings 30, of a shape approximating the contour ofthe heads. The free end of the shaft or pole is then lowered intoworking position, when, it will be seen, it is securely held fromwithdrawal, while the necessary play is permitted, for it cannot beremoved 8o from the bearings 30 until it is held vertical.

The spring-extension 2O of the clip 17 bears against the rear extremityof the thill, as shown in Fig. 2, thereby forming an antirattler. 8 5

Having thus described myinventio'n,what I claim as new, and desire tosecure by Letters Patent', is-

1. A thill coupling, consisting of jaws adapted to hold the pole orshaft and having 9o recesses at their upper ends, a baseplate adapted toextend underneath the axle and connected with said jaws and having anaperture near its rear end, a bolt extending loosely through saidaperture, a clip engaging said bolt and adapted to extend over the axle,the said clip being provided with ears arranged to enter the recesses inthe jaws, and means for locking said bolt, as set forth.

2. In a thill-coupling, the combination of roo the jaws and base-plate,a clip arranged for engagement with the jaws at one end, a boltconnected to said clipat its otherend and extending through thebase-plate, a nut screwing on the lower end of said bolt and formed withtrunnions, and a locking-lever mounted on said trunnions and havingcam-surfaces adapted to ride on the lower face of said base'- plate,'asset forth.

3. A thill-conpling,comprisinga base-plate and thill -holding jaws,which latter are formed with recesses at their upper ends, a clipadapted to rest on the axle and having ears arranged to enter saidrecesses, and a connection between the rear of the base-plate and therear of the clip, as and for the purpose set forth.

4. A thill-cou pling,co1nprisinga base-plate and thill-holding jaws,which latter are l'ecessed at their upper ends, a clip provided withapertured ears at its front end adapted to enter said recesses, and anapertured rear end, and a notched bolt detachably connected to thebase-plate and engaging the apertured rear end of the clip, as setforth.

5. A thill-coupling, consisting of spacedapart jaws adapted to receivethe pole or shaft, and a base-plate adapted to extend underneath theaxle, anda clip arranged for connection to the rear of the base-plateand having apertured ears adapted to engage the upper ends of said jawsand an extension beyond said ears, said extension forming anantirattler, as set forth.

6. In a thill-couplin g, the combination with the jaws having verticalpassages enlarged at their lower ends, of a pole or shaft having anon-circular or flattened opening in its rear end, and a pivot-pinhaving a correspondingly-shaped shank fitted in said opening, and afixed attened head and a detachable flattened head on said shank adaptedto be inserted in said passages, as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

VINSTON KENT PENDLETON.
